1. support buffer_size set by user 2. support assigned chn 3. support udma read 4. support buffer address set by userspace Need to update test_pcie and test-pcie-ep-new. New test command: 1. run ./test-pcie-ep-new 500 1024 chn_num buffer_address both on RC and EP first Release buffer use dma channel number = chn_num. if buffer_address = 0 pcie_dma_buffer_address get from DT reserved memory else pcie_dma_buffer_address = buffer_address 2. run ./test-pcie 1 1000 1024 1 chn_num on RC The last "1" means enable PCIe udma read, "0" means write. RC read from EP use dma channel number = chn_num. 3. run ./test-pcie 2 1000 1024 1 chn_num on EP EP read from RC with offset = buffer count * buffer size. 4. check version by: cat /sys/kernel/debug/pcie/pcie_trx | grep version 5. 1024 means set buffer size to 1MB.
